Description of problem:
==================
With uss enabled on gluster volume, when compressing a directory of files into a tar ball, I still see tar complaining "file changed as we read it"


How reproducible:
==================
always on my testbed

Steps to Reproduce:
===============
1.created a 4x3 volume 
2. enabled uss and quotas
3. mounted volume on 4 clients and started to untar kernel image and again tarball the image.

When tarballing the files back, i see the above issue consistently
